Do you by chance have an electric fan? If so, disconnect the fan and then start and stop the engine and see if that fixes your problem. Sometimes the fan still spinning on shutdown bleeds voltage over to the ignition and or MSD. If this is your problem, you can install a diode or relay on the electric fan and this will solve your issue.
